ORSANCO sets Pollution Control Standards for industrial and municipal waste water discharges to the Ohio River, and tracks certain dischargers whose effluent can seriously impact water quality. The standards designate specific uses for the Ohio River, and establish guidelines to ensure that the river is capable of supporting these uses. To keep pace with current issues, ORSANCO strives to review the standards at least every three years. As part of the review process, workshops and public hearings are held for public input.
